BSOD at login screen

My friend's laptop is getting blue screen at the login screen. I can't find a tool to debug or view the dmp files so I was hoping someone could tell me what it is that's causing the issue. Attached are the dmp files.

The latest dump files list SRTSPL.SYS as the probable cause. This is a Symantec AutoProtect driver. Old and incompatible drivers can and do cause issues with Windows 7, often giving false error codes. Random stop codes can often indicate hardware issues.

As a Priority:

Norton is known to be a cause of BSOD's on many Windows 7 systems. I suggest that you uninstall Norton using the Norton Removal Tool in Safe Mode. Download Blue Screen friendly Microsoft Security Essentials as its replacement. Make sure Windows firewall is enabled!

Thank you very much for the help. After removing Symantec in Safe Mode the laptop booted up fine and I have updated the drivers of the devices you listed. Hopefully it will keep working fine for a while. Again, thank you very much for the help.
